* Allow redefinition of a typedef with the same name.Bernhard Schommer2015-10-043-7/+53
| | | | | C11 allows a typedef redefinition if the types are the same. We now allow this also and issue a warning and an error if the types are different.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | was not parsed correctly: typedef int a; int f() { for(int a; ;) if(1); a * x; } Additionnaly, I tried to add some comments in the pre-parser code, especially for the different hacks used to solve various conflicts.

| * Avoid problem with implict declarations.Bernhard Schommer2015-09-302-4/+18
| | | | | | | | | | | | In order to avoid the problem that the stamp is not correct for implict declarations I insert all possible stamps of a function into my mapping and assign them one debug id.
| * More fixes for the DebugInformation.Bernhard Schommer2015-09-294-20/+38
| | | | | | | | | | | | | | Changed the sizeof function to take into account the bytes needed for the sleb128/uleb128 encoding of the DW_OP_* arguments and changed the end_live_range function to only close functions where the live range is currently open.

| * Change the way the debug sections are printed.Bernhard Schommer2015-09-2815-179/+228
| | | | | | | | | | | | If a user uses the #pragma use_section for functions the diab linker requires a separate debug_info section for each entry. This commit adds functionality to emulate this behavior.

| * More refactoring of the Debug Information.Bernhard Schommer2015-09-274-51/+103
| | | | | | | | | | | | | | In order to remove unnecessary dependecies the implemenation type is made and the DebugInit file initializes the fields in the record. This allows it to move more functions behind the Debug interface without introducing circular dependencies.
| * Added printing the reference address for the LocRef and started refactoring oldBernhard Schommer2015-09-279-111/+37
| | | | | | | | | | | | | | | | Debuging code. The old functions to store the symbol for the Global variables and retrive this is no longer needed since the atom is stored in DebugInformation. Also the Debug.Abbrev module is no longer needed.

| * Added support for the locations of stack allocated local variables.Bernhard Schommer2015-09-2516-98/+318
| | | | | | | | | | This commit adds furher support for location information for local variables and starts with the implementation of the debug_loc section.
| * Added placing labels for live ranges etc.Bernhard Schommer2015-09-245-9/+152
| | | | | | | | | | In order to avoid the usage of too many labels we replace the debug statements during the Asmexpand phase.

| * Added support for printing local variables and fixed issue with .textBernhard Schommer2015-09-236-11/+27
| | | | | | | | | | | | Local variables are now added with bogus lexical scopes to reflect the actually lexical scopes. Also this commit fixes assembler problems of the das when a user section with the name ".text" is defined.

| | * Continuing experiment: track the scopes of local variables via __builtin_debugXavier Leroy2015-09-212-39/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As observed by B. Schommer, it is not enough to track scopes for every source line, as blocks can occur on a single line (think macros). Hence: - Revert debug annotations of kind 1 to contain only line number info. Generate them only when the line number changes. - Use debug annotations of kind 6 to record the list of active scopes (as BA_int integer arguments to __builtin_annot). Generate them before every nontrivial statement, even if on the same line as others. - Remove the generation of "variable x is declared in scope N" debug annotations. This can be tracked separately and more efficiently.
| * | Record the scope structure during unblocking.Bernhard Schommer2015-09-2214-65/+173
| | | | | | | | | | | | | | | | | | Instead of creating separate annotations for the local variables we call the Debug.add_lvar_scope and we construct a mapping from function id + scope id to scope information.

| | * Experiment: track the scopes of local variables via __builtin_debug.Xavier Leroy2015-09-205-74/+181
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C2C: the code that insert debug builtins with the line numbers is now in Unblock. Handle calls to __builtin_debug. Unblock: generate __builtin_debug(1) for line numbers, carrying the list of active scopes as extra arguments. Generate __builtin_debug(6) for local variable declarations, carrying the corresponding scope number as extra argument. Constprop: avoid duplicating debug arguments that are constants already. PrintAsmaux: show this extra debug info as comments.
| * | New version of adding scopes etc.Bernhard Schommer2015-09-204-16/+63
| | | | | | | | | | | | | | | Instead of reimplementing the whole scope handling in the debug information use the existing functionality and fill the scopes explicitly in the functions.
| * | Started implementing the scope for the Debug Informations.Bernhard Schommer2015-09-186-13/+109
| | | | | | | | | | | | | | | | | | Scopes will be handled by a stack of all open scopes. This stack then can also be used to generate the debug directives to track the scopes through the rest of the passes.
| * | First version with computation of dwarf info from debug info.Bernhard Schommer2015-09-1714-636/+370
| | | | | | | | | | | | | | | Introduced a new dwarf generation from the information collected in the DebugInformation and removed the old CtODwarf translation.
| * | Move more functionality in the new interface.Bernhard Schommer2015-09-1615-75/+120
| | | | | | | | | | | | | | | | | | Added functions to add more information to the debuging interface, like the struct layout with offsets, bitifiled layout and removed the no longer needed mapping from stamp to atom.
| * | Add the debug interface file.Bernhard Schommer2015-09-165-12/+177
| | | | | | | | | | | | | | | | | | | | | | | | The new file Debug.ml contains the interface for generating and printing debug information. In order to generate debug information the init function initializes the necessary functions depending on the -g flag. If the -g is not there all functions are dummy functions which do nothing.
